How do you make bokeh hearts like this?

Question

I have a Pentax K110D and I see people doing this all the time and have no idea how to do it myself. Does anybody know how?

Answer 1

The person who posted that photograph explains exactly how they did it in one of the comments: http://www.diyphotography.net/diy_create...

I hope that helps you get the effect with your camera.
